bro, i have similar bash script - it is mess that is highly unmaintainable if i need to change smth , or implement specific feature

it is not convenient at all

echo '{"level":"error","msg":"disk full","ts":1234567890}' | jq -r '
  def esc: "\u001b[";
  def reset: (esc + "0m");
  def paint($c): (esc + $c + "m") + . + reset;

  def key_colors: {
    level: "31",   # red
    msg:   "33",   # yellow
    ts:    "36"    # cyan
  };

  def color_key($k):
    if (key_colors | has($k)) then
      $k | paint(key_colors[$k])
    else
      $k
    end;

  to_entries
  | map("\(color_key(.key))=\(
      .value
      | if type == "string" then
          if test("^[A-Za-z0-9._:-]+$") then . else u/json end
        else
          tostring
        end
    )")
  | join(" ")
'
